Glutamate receptor delta-1 subunit also known as GluD1 or GluRδ1 is a protein[4][5] that in humans is encoded by the GRID1 gene.[6][7]


This gene encodes a subunit of glutamate receptor ligand-gated ion channel. These channels mediate most of the fast excitatory synaptic transmission in the central nervous system and play key roles in synaptic plasticity.[6]

Clinical significance

Several genetic epidemiology studies have shown a strong association between several variants of the GRID1 gene and increased risk of developing schizophrenia.[8][9]
